[Serusers] SER Presence

Hi all, Now that my routing problems seems to be gone, I ran into some presence issue. It seems the presence mechanism is working well, meaning I created the DB tables to store the informations, I added some lines in my conf (see below) and now I'd like my users to be able to send presence info each other WITHOUT an xcap server. I naturally wanted to add modparam("pa", "auth", "none"). But, as I understood, it seems this option is no longer exported in the lastest SER Version. So, how can I do ? Is it now mandatory to have an xcap server running ? Thanks alot. if (method == "SUBSCRIBE") { # create transaction state; abort if error occured xlog("L_INFO", "\n[SER]: --SUBSCRIBE--: Time: [%Tf] Method: <%rm> R-uri: <%ru> Contact Header: <%ct> From: <%fu> To <%tu>\n\n"); if ( !t_newtran()) { sl_reply_error(); break; }; if(!handle_subscription("registrar")) { sl_reply_error(); break; }; break; }; if (method == "PUBLISH") { # create transaction state; abort if error occured xlog("L_INFO", "\n[SER]: --PUBLISH--: Time: [%Tf] Method: <%rm> R-uri: <%ru> Contact Header: <%ct> From: <%fu> To <%tu> \n\n"); if ( !t_newtran()) { sl_reply_error(); break; }; if(!handle_subscription("registrar")) { sl_reply_error(); break; }; break; };
